    • Failing to fully isolate the water supply before starting work, leading to potential flooding or incomplete isolation.
    • Using incorrect pipe sizes or mixing incompatible materials (e.g., galvanic corrosion from dissimilar metals) without appropriate insulation or fittings.
    • Neglecting to incorporate service valves on fixtures, making future maintenance more difficult and often an assessable oversight.
    • Providing quotes without allowing for waste disposal or minor sundries, resulting in inaccurate project costs.
    • Overlooking the need to check for hidden pipes or cables before drilling, which can cause damage and safety hazards.
    • Overlooking the need to check mains water pressure before quoting, leading to inadequate system design or unexpected costs.
    • Failing to measure and plan pipe runs accurately, resulting in material waste or poor fit.
    • Using incompatible materials (e.g., connecting copper to galvanised steel without dielectric unions) causing corrosion.
    • Neglecting to test for leaks thoroughly or skipping the inspection of hidden connections.
    • Not considering building regulations or water regulations when installing kitchen appliances.
    • Underestimating material quantities and labour time, leading to inaccurate quotes that cause budget overruns.
    • Neglecting to check water pressure and flow rates before designing the system, resulting in poor performance.
    • Using incompatible materials (e.g., joining copper to steel without dielectric unions) causing corrosion.
    • Failing to isolate the water supply and drain down the system before starting work, leading to flooding or property damage.
    • Failing to isolate water and electrical supplies fully before starting work, leading to safety risks and water damage.
    • Misidentifying pipe materials and subsequently using incompatible fittings or joining methods, causing future leaks or corrosion.
    • Underestimating material costs or forgetting to include waste disposal and sundries in quotes, reducing profitability.
    • Neglecting to check pipe alignment and fall when installing drainage, resulting in poor flow and blockages.
    • Omitting to pressure-test new pipework before sealing walls or floors, which could necessitate costly rework.
    • Underestimating the significance of pre-work checks, leading to unexpected issues such as incompatible pipe sizes or hidden structural obstacles.
    • Quoting inaccurately by omitting essential components like fittings, sealants, or waste disposal fees, resulting in unprofitable or uncompetitive bids.
    • Selecting incorrect tools or materials for the task, for example using compression fittings where soldered joints are required, often due to inadequate technical knowledge.
    • Rushing practical tasks without testing connections, causing leaks or system failures that require costly rework.
    • Neglecting to review completed work thoroughly, missing opportunities to rectify minor defects or learn from errors for future improvement.
    • "Health and Safety is just common sense." Many students underestimate the depth and specificity of health and safety regulations. It's not just about avoiding obvious dangers; it involves understanding legal responsibilities, conducting formal risk assessments, implementing control measures, and knowing emergency procedures for specific site conditions and tasks. Examiners look for detailed knowledge of legislation and its practical application, not just a general awareness.
    • "Basic electrical work is easy and doesn't require much caution." While this qualification covers *basic* electrical tasks, the risks associated with electricity are severe.
